His friend, off-duty Lemoore Police Officer, Jonathan Diaz, 31, and Trevino’s father, Ramiro Trevino Sr., were able to rescue his girlfriend from the room the couple was in.

The Kings County Sheriff’s Office says Trevino Jr. was beating and choking her. Immediately after getting the victim outside of the home, they heard a gunshot from inside.

“Diaz and Trevino Sr. immediately ran back into the residence upon hearing the gunshot to check on Trevino Jr. Upon entry into the residence Diaz and Trevino Sr. encountered Trevino Jr. who had armed himself with multiple firearms. While attempting to diffuse the situation Diaz was fatally shot and Trevino Sr. was shot and critically injured. After shooting Diaz and Trevino Sr., Trevino Jr. committed suicide by shooting himself in the head,” said a press release from the sheriff’s office.

Trevino Sr. died Nov. 4 after being treated at Kaweah Delta Medical Center in Visalia.
